4Application mea March' 3o, isos. serial No. 424,031.'

To all Awhom it-may concern:

Bc it known that I, CARLJ. BA RTON, a citizen of the United States, residing atBig Rapids, in the county of Mecosta and State of 5 Michigan, have invented an Improvement in Gas-Mantle Supports, of which the following is a specification.

As is wellknown, the so-called gas mantles attached to gas burners for intensifying the brilliancy of the llame, are very brittle and liable to be cracked or broken cil' when jarred or otherwise set suddenly in vibration. To avoid this result, and thus prolong the life of such mantles, I have devised an imurncr. .y

The invention alsoyinclndes an improved construct-ion and combination of parts where-- by I provide for convenient attachment of the mantle support to a lnirner and detachment of the same therefronr the support being held firmly on the burner vhile in use.

The construction and combination of p arts embodying the invention as afwhole are hereinafter described, and the `vnovel features specifically indicated in the claims.y

In the accompanying drawing, Figurel is a side view showing my improved attachment 'for a pendent burner, the parts being inclosed in a= glass globe which is shown artly broken away. liorizontal section on the ll'ne 2-2 of Fig. 1. Fig. 3 is a cross section on the line 3-3 of Fig. 2. Fig. 4 is a perspective view-part support.

' In the several-figures of the drawing, A indicates the mantle proper, B the sup o1 therefor, and C a pendent burner to w rich 40 the supportis applied. The mantle may be constructed in tne usual manner and of the usual materia-ls; and its top edge is attached at 1, to the inner ring 2, of the support B. This ring is pivoted at opposite points 3, toa

ring-4, and the latter is in turn pivoted at opposite points 5 to an outer ring 6. It will be noted that thepivotal points 5 are arranged 90 from the pivots 3 of the inner or mantle ring. Thus the support B, so far as described,`is practically identical with the wellknown gimbal commonly employed for supporting a shipz's compass, and for various other pu oses when it is desirable to provide for vi )ration or swinging of a suspended object in any direction. The inner or man- Specication'of Letters Patent.l

outer .ring 6 is constructed of the same mate. rial. In other words, these two rings are practically constructed of porcelain, while the middle or intervening ring 3 is formed of 50 plate metal. A distinguished feature of the outer ring is the provision of integral prongsl or arms 7 that extend upward and then inward, the same being three in number and but separated by a distance slightly exceeding the diameter of the upper portion 8, of the burner C. Such part 8 is provided with vertical grooves 9 in whichthe inner ends of the arms, or prongs, 7 are adapted to slide up 70 or down, and between the grooves 9 are thickened or enlarged portions having recesses 1() in their upper edges for holding the ends ofthe arms 7. As shown in Figs. 1 and 2, the mantle support has been applied to the, burner C by sliding the inner ends of the arms 7 upward in the three correspondingly vertical grooves 9, and then rotating the su port a fraction of a circle, or until, the said arms Adrop into the recesses 10, when they are held S0 from lateral movement. Thus the outer .orc-elain ring of the gimbal suppo'rtB is held irmly or immovably in horizontal position, while the metal ring 3 is free to move or swing in a vertical plane, as is also the inner porce- S5 lain mantle ring 2.

It will be apparent by the construction, arrangement, and combination of parts above described, that the pendent mantle A is suspended in such manner that it may rock or go vibrateK freely in any direction laterally, which enables it to successfully resist jars or sudden movements of the burner from any cause, so that it is not liable to be cracked or broken as when suspended immovably.v It is further apparent that by means of the support B, constructed as shown and described, the whole attachment may be easily applied to and quickly removed from a burner and quired horizontal position when in place as indicated in Fig. 1.

What I claim is:

1. The combination, with an inverted burner having its body provided with vcJ-e` tical grooves and intervening thickened portions having recesses in their upper edges, of a metal mantle-support comprising rings pivoted together to ferm a gimbal, or uniy versal joint, the outer lring having inward-ly projecting convergent arms adapted to slide tle ring 2 is formed of burnt clay, and the upward in the grooves of the burner and to their ends converging to a common center, 65"Y that it is nevertheless held lirmly in the re- 100 seat on the recessed portions'of lthe same, snhstantiall f" as described.

2. The `combination, with a burner, ofa gas mantle and support therefor,

the latter comprising parts f orming'a 1mi-V 4ycrsal joint that allows the mantle proper to rock laterally 1n any direction, the outer portion of such joint having projectionsthat engage thel burner detachably, as shown and described.

3. The improved gas-mantle support comprising an inner ring and a Surrounding ring which are pivoted together at opposite points, and a third or outer ring to which the intermediate ring is also pivoted so as to form a "universal joint, .the outer vring being constructed with inwardly proj eeting convergent arms, adapted for attachment to a burner, substantie ly as described.

. \\.L`\ V l 4. The improved gas-mantle support, coml:

prisingjr three rings which are pivoted together to form a gimbal and the outer ring provided.

with devices adapt'eil for lctaehable engagenient with a pendent burner, vsubs'mntially is pivot'ed both to the inner and outer ones,

substantially as described.\
